# --description--

请注意，到目前为止你添加到页面的所有内容都在 `body` 元素内。 应该呈现到页面的所有页面内容元素都放在 `body` 元素中。 但是，其他重要信息位于 `head` 元素中。

The `head` element is used to contain metadata about the document, such as its title, links to stylesheets, and scripts. Metadata is information about the page that isn't displayed directly on the page.

在 `body` 元素上方添加一个 `head` 元素。

# --hints--

你删除了 `body` 元素，或者它缺少开始标签或结束标签。

```js
assert(document.querySelector('body') && code.match(/<\/body>/));
```

你的 `head` 元素应该有一个开始标签。 开始标签的书写语法为：`<elementName>`。

```js
assert(code.match(/\<head\>/));
```

你的 `head` 元素应该有一个闭合标签。 结束标签在 `<` 字符之后有一个 `/`。

```js
assert(code.match(/\<\/head\>/));
```

你的 `head` 元素应位于 `body` 元素开始标签的上方。 你把它放在别的地方了。

```js
const noSpaces = code.replace(/\s/g, '');
assert(noSpaces.match(/\<\/head\>\<body\>/));
```
